Medición de los niveles y curva de Co2 con el uso de máscara laríngea y tubo endotraqueal en pacientes de 14 a 60 años del Hospital Vicente Corral Moscoso, Cuenca 2018

Abstract

Introduction: there are few studies about the variability that exists between capnography and capnometry during the use of the laryngeal mask and endotracheal tube, that’s why it has been considered important to perform this research. Objective: to determine the changes in the levels and curve of expired carbon dioxide (EtCO2) referring to the use of the laryngeal mask (LMA) and the endotracheal tube (ET). Methodological design: a descriptive cross-sectional study was carried out from january to december 2018. The population was made up of a representative sample of patients undergoing balanced general anesthesia procedures. Data from 180 patients were analyzed with the Statistical Package for the Social Sciences (SPSS).Results: in the analysis of the capnography, there was no difference between the two evaluated groups, 2 patterns of bronchospasm were found during the fifth- and thirtieth-minute during surgery with values of p = 0.363 in both cases. Capnometry averages were obtained in the TET group and LMA, with the following results: at minute 5 an average of 36 ± 4 mmHg and 36 ± 3 mmHg with p = 0.324, at minute 30 a value of 35 ± 4 mmHg and 35 ± 3 mmHg with p = 0.517 and at minute 60 a value of 35 ± mmHg and 34 ± 3 mmHg with p = 0.84 respectively. Conclusions: it was concluded that the results of capnography and capnometry do not vary depending on the use of the laryngeal mask and endotracheal tube.
